Chalk up another one… for the 20th time this year, Boston cracked the 90 degree mark yesterday. The record for 90 degree days in a year is 30, set in 1983. With September still looming and the potential for some solid mid-month warmth, we’ll likely add at least a couple more 90 degrees days next month before the shorter days and longer nights eventually get the best of the lingering summer’s heat. In the meantime, without another drop of Boston in Boston through Wednesday, it’ll likely go down as the driest summer on record, edging out the top spot of 1957. In 1957, only 3.97″ of rain fell all summer (Meteorological summer = June, July, August), this year, we’ve only picked up 3.92″ in Boston.
In terms of any rain potential this week, the best chance is Thursday as scattered showers and storms are possible as a cool front slides on in. Behind the front, we’ll get a taste of early Fall as September starts off close to seasonal levels, if not slightly below it with high temps in the 70s and lows in the 50s. Temps should warm back into the 80s by Labor Day and will likely be warmer than average after that, into the middle part of the month.
In terms of the tropics, we have some action out there, but no promising signs of tropical moisture climbing into New England to bring us appreciable rains over the next week as moisture from both TD 8 and TD 9 likely stop short of southern New England thanks to the late-week front kicking things out to sea. Gaston has produced large swells in the Atlantic, so if you’re heading to the beach over the next few days, careful of the risk of rip currents.
